The 25-year-old golf great, in just five years as a professional, should whiz past that career-earnings mark in a matter of weeks.

With his income averaging $50 million annually in his first five years, Woods knocked top-earning Michael Jordan off the throne a couple of years ago.

And while he trails Jordan in career earnings – about $450 million – most sports-business professionals have been predicting Woods will blast past that to become the world’s first $1 billion athlete.

Tiger’s take has risen steadily since he turned pro in 1996, with the figure hitting around $75 million this year. Given that, and the prospect of 25 years or so of productive golf still ahead of him, the $1 billion mark seems like a gimme.

Woods, believe it or not, could earn $2 billion by the time he turns 50, a review by The Post of his current and pending deals reveals.

Tiger gets about $66 million – most of his annual bounty – from his stable of corporate “partners” such as Nike, Buick and Wheaties, whose products he hawks. That estimate also includes the estimated $10 million a year from an upcoming deal with Disney.

Another $6 million or so comes from golf-tournament winnings. The remaining $3 million comes from appearance fees from overseas tournaments.

Assuming he golfs in 23 tournaments a year, which he did last year, here’s how his $75 million a year breaks down: $3.26 million per four-day tournament; $815,000 a day, or $163,000 an hour, based on a five-hour workday.

Nobody signing the checks is complaining – not the networks who seed the winnings pools, not Tiger’s corporate partners, like Nike, who pay Woods a reported $20 million a year to use their clothes and balls, and not the public who can’t get enough of him.

“Nike could pay double their fee and still get good value,” said Doug Shabelman, an executive with Burns Sports & Celebrities, based in Chicago.

For example, Nike went from zero to 5 percent of the $1 billion golf-ball market after signing Woods. Not too shabby.

Recognizing this, Disney is ready to offer Woods a megadeal to create golf programming on its ABC network.
